fix(tests): host PDF fixture via jsDelivr with proper application/pdf MIME

Browse source 
Raw github serves application/octet-stream which OpenAI/Gemini reject
when LiteLLM fetches the URL client-side. jsDelivr serves the same
file with content-type: application/pdf. Pin to a commit SHA so the
asset is immutable and jsDelivr can cache it for a year.

# - raw GitHub returns Content-Type: application/octet-stream,
# which OpenAI/Gemini reject when LiteLLM fetches the URL
# client-side and forwards the bytes.
# - Wikimedia URLs intermittently return 400 from Anthropic's
# server-side URL fetcher.
# The URL is pinned to a specific commit SHA so jsDelivr can
# serve it as immutable (cache-control: immutable, max-age=1y).
